I would say it is very useful.
- It has the potential to build the bond between you and your readers, and continue building even as your blog grows and readers change
- It cures writers block, just look at your Skribit and see some interesting ideas to write about
- It is simple, loads really quick and allows for every reader to view and participate
- Helps you find out what other people see as something very cool (SW Reality Show) that you just may have brushed off
So if you are still on the fence about using Skribit, try it out for a week or two. Your readers will love you.
